Access and field sizes

Greetings-

I'm in the process of porting a database from Access to postgres, and have
run into a snag. The snag involves boolean fields using checkboxes in
Access forms; they always return a useless Microsoftish error:

The field is too small to accept the amount of data you attempted to add.
Try inserting or pasting less data.

This happens when a checkbox is clicked to set a boolean value to True,
but not when it is clicked to set the value back to False.

Does anyone have any experience or idea where to go with this?

Thanks-
Andy Perrin
